XC9572XL-10PCG44I

Overview

The XC9572XL-10PCG44I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 72 macrocells, 1600 usable gates, and 34 user I/O pins within a 44-pin PLCC package. The device operates at a supply voltage of 3.0V to 3.6V with a maximum propagation delay of 10 ns and a system frequency up to 178 MHz. It utilizes Flash memory for non-volatile storage, supports in-system programming via JTAG, and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• 72 Macrocells with 1600 usable gates across 4 Logic Array Blocks
• 10 ns maximum propagation delay supporting frequencies up to 178 MHz
• Flash-based non-volatile technology enabling unlimited reprogramming cycles
• Industrial temperature range operation (-40°C to +85°C)

Applications

• High-performance logic replacement in industrial control systems
• Address decoding and bus buffering in computing systems
• State machine implementation for embedded controllers

Procurement Notes

Verify component authenticity due to discontinuation status. Confirm package integrity as PLCC packages may show wear. Check for RoHS compliance if required by current manufacturing standards. Ensure programming equipment supports JTAG interface for configuration.

Selection Notes

Select this variant for designs requiring 10 ns speed grade within a 44-pin PLCC footprint. Compare against XC9572XL-5 or -7 variants if faster switching is needed. Verify that 34 I/O count meets interface requirements. Consider thermal management for industrial environments exceeding standard commercial limits.

Part Context

This part belongs to the XC9500XL high-performance CPLD series, which succeeded the original XC9500 family. The XL series introduced Flash technology, eliminating the need for external EPROM programmers and allowing in-system programming. The XC9572 model specifically offers a balance of density and speed for mid-complexity logic applications.
